• New 'info' option to see the characteristics of a compressed bitstream
• Optimized LZ codec improves compression ratio
• Re-written multi-threading internals provide a performance boost
• Hardened code: more bound checks, fixed UBs: decompressor more resilient to invalid bitstreams
• Much better build (fixed install on Mac, fixed man page install, fixed build on FreeBSD & minGW, added ctest to cmake, etc...)
• Improved portability
• Improved help page
